|
Cerebrum
|
majority of brain, consists of frontal parietal temporal and occipital lobe
|
|
|
cerebellum
|
located posterior, inferior
|
|
|
12 cranial nerves
|
OOOTTAFAGVAH
Olfacory, Optic, Oculomotor, Trochlear, Trigeminal, Abducens, Facial, Auditory, Glossopharyngeal, Vagus, Accessory,Hypoglossal |
|
|
Piamater
|
Adheres to meural tissue
|
|
|
Arachnoidmater
|
weblike, seperated from piamater from CSF,
|
|
|
duramater
|
fibrous periosteal layer, contiguous with spinal column
|
|
|
cerebral cortex
|
in forbrain
plays a key role in memory, attention, perceptual awareness, thought, language, and consciousness.Grey matter. |
|
|
Forebrain
|
telencephalon and diencephalon
|
|
|
thalamus
|
Sleep, wakefulness, consciousnesnn, arousal, wakefulness,
damage =coma |
|
|
hypothalamus
|
links neuro system with endocrine system, contains pituitary, controls body temperature, hunger, thirst, [1] fatigue, anger, and circadian cycles.
|
|
|
pons
|
relays info between cerebrum and cerebellum:
regulates respiration, |
|
|
microtubules
|
largest "bone" in a cell
|
|
|
neurofilaments
|
"bone" found in neuron only
|
|
|
Microfilaments
|
smallest "bone" in cell
|
|
|
Terminal arbor
|
tree formed by network of axons
|
|
|
stellate
|
star shaped dendrite structures
|
|
|
Walerian degeneration
|
distal end of severed axon degerates, no protein is being formed.
|
|
|
pyramidal
|
pyramid shape dendrite structure.
|
|
|
Kinesin
|
fueled by atp takes thing from cell body to axon terminal. Moves by synaptic terminal = anterograde transport
|
|
|
Glial cells
|
outnumber neurons 10 fold,
|
|
|
Dynine
|
retrograde transport motor on microtubules. goes from axon terminal to soma, Rabies and Herpies use this system to spread. then up the next dendrite etc.
|
|
|
Astrocytes,
|
Glial typsfill the spaces, influence neuroite growth, regulate chemical content of extracellular space.
|
|

Dendrite
|
Greek for "tree",

|
|
micorglia
|
phagocytic, help with immune play a role cell migration during development of brain.
|
|
|
Resting potential
|
1/1000 of a second. Inside of membrane is hyperpolarized compared to outside.
